Please help me if you can. For some reason my media player no longer allows me to burn CD's. I had been able to do so before without any problems. It asks me to connect a burner and then retry. My computer is a brand new Leader Discovery 2430 and my operating system is Windows Vista. I've checked my drivers, and I notice that there is a yellow triangle next to the HL -DT -ST DVD-RAM GH22NS30 Device. When I check it's properties, under the "General" tab it says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" I still have the original disk that came with my computer. However, the computer won't recognize it. It doesn't run automatically when I put the disk in and when I go to "My Computer", the driver that you put CD's into seems to be missing- or else it isn't working at all, because all the drivers I select ask me to load a disk even though one is already in. If there is anyone who can give me step-by-step instructions as to what to do I would really appreciate it.
